The key is the red standby light, a little red light at the edge of the TV that you aim the remote at. In normal use, the red standby light is on when the TV is off (indicating the TV is on standby), and the red standby light is off when the TV is in use (or doesn’t have power).
If a Red LED is blinking and the TV is not working properly it means that the TV has detected an issue or problem. Most Red LED blink conditions require service. The meaning of the blink codes differs between TV models. However, the number of blinking times is mostly 2 to 8.
Hold down the “Exit” button for 12 seconds if you want to point the remote control at the TV. The TV can be reset with the “enter” button on the remote control. The unit will stop operating.

Method 1. Press and hold the power button on your remote until the TV turns off and on again. This should only take about 5 seconds.
Although Samsung TVs are popular, especially among people looking for smart TV products, some users experience issues with their remote controls. The most common problem is a blinking red light on the remote. This light means that the remote is out of range or the battery is low or it can be any other problem.
If your Samsung remote keeps saying that it is not available, turn your television set off and allow it to completely drain of power. Once this is completed, turn the TV back on and simultaneously hold down the ‘Return’ and ‘Play/Pause’ button on the remote control as the TV starts back up.
